Perhaps the iBooks will feature the same Core Duo processor, but be clocked significantly lower -- 1.2 to 1.6GHz range. The iBooks' battery life would then be a selling point of the computer -- like it was with the iPod photo over the monochrome 4th generation iPod (what was it -- like 8 to 10 hours vs. 15 hours on the photo model?).
Steve showed us that the G4 scored ~0.26 on performance per watt, while the Core Duo scored over 1.0. They boosted the brightness (and quality?) of the screen, though, so I'd expect the battery life to be somewhere close to what it is currently... so while the processor may be more power efficient (is it?), the screen surely sucks up more power than previous generations. Hopefully we'll know in early February!
